When he finds out that she's going to a horror party, he tells her that he already has someone to hang out with. He's not worried about his own relationship status, he says. He wants someone who has an "Aura" , which is a fancy term for a good vibe. He doesn't want a blind date, he wants someone he already likes. The party is going to be a "horrible" one, and he wants to make the most of it. He can't wait to make new friends.
